' Be it known that 1, JAMES. ANDERSON, a

subject of the King oi Great Britain, residing Wheeling, in the countyof Ohio and State of West Virginia, have inventedcertain new and usefulImprovements in Soot Blowers; and I do declare the following to be afull, clear and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. i

My invention relates to improvements in devices for removing accumulatedsoot from water tubes of fuel economizers or feed water heaters, and myprincipal object is to provide a simply constructed and ineXpensive sootblowingdevice which may be easily installed without alteringtheconstruction of the economizer, and adjusted vertically 2 to blow thesoot fromthe tubes.

Another object is to provide supports for the blower adjusting means,secured to certain of the usual closing plugs of the upper headers ofthe economizenso that it is unnecessary to drill any holes whatever insaid headers in order to attach said supports.-

V'Vith the foregoing and minor objects in view, the invention resides inthenovel construction and arrangement of parts hereinafter described andclaimed and shown in the accoinpanying drawings.

tion of an economizer showing the soot blower applied thereto.

Fig. 2 is a vertical transverse section on the plane of line 2-'2 ofFig. 1.

Fig. 3 is a horizontal section on the plane indicated by line 3-3 ofFig; 2.

Fig. at is a perspective view of one of the nozzles which direct fluidunder pressure against the water tubes.

In the drawings above briefly described, I

have shown a portion of a well known fuel economizer or feed water,heater, including spaced upper and lower headers 1 and 2 and water tubes3 connecting them. The spaced parallel upper headers 1 are provided withthe usual plugs 4L in their upper sides for giving access to the tubes 3and I utilize 5 which carry bearings 6 for a rotary shaft 7. this shaftbeing driven by any preferred means, such as indicated at D in Fig. 1.The standards 5 are by preference of, angle iron r and their lower endsare equipped with flat I igure 1 is a longitudinal section of a por--certain of these plugs to anchor standards 5- horizontal feet 8 restingon the headers l and securedto the adjacent plugs l, by capsorews or thelike 9. By attaching the standards to the economizer'in this manner, itis unnecessary to drill any openings whatever in the headers l andconsequently they are in no manner weakened, and it will be observedthat the feet 8 and screws 9 serve to hold the adjacentplugs in place.

Chainsor the like 10 depend from the shaft 7 and are verticallyadjustable by turning said shaft, sprockets 11 being preferably providedfor said chains as shown. The lower ends of the chains are connectedwith vertical rods 12 received slidably between the headers 1, and thelower ends of the rods 12 pass through the centers of horizontal lifterbars 13 andare provided with nuts 14 by means of which adjustment maybeefl ected to place all of the bars 13 in the 7 same horizontal plane.These bars support an appropriate number of zig-zig pipes 15 havingpairs of outwardly diverging nozzles 16 for directing fluid underpressure against the tubes 3. Thave shown two pipes 15, one end of saidpipes being closed by suitable caps or plugs 17 while their oppositeends are connected by a cross pipe 18. At 19, a jointed pipe 20 isconnected with the pipe 18 for supplying fluid under pressure to thispipe and consequently the pipes 15 so that such fluid will be directedagainst the tubes 3 by the nozzles 16. thereby ef-' fectively removingthe accumulated soot. As the shaft 7 is turned in one direction, thechains 10, rods 12 and lifter bars13, move the pipes 15 vertically alongthe tubes so that the latter may be cleaned from one end to the other,this movement of parts being aerniitted by the jointed nature of thepipe 20. The rods 12 and parts supported thereby descend by gravity whenthe shaft 7 is retrogradely rotated.

The nozzles 16 are preferably constructed as seen in Fig. 40, from shortsections of pipe flattened at one end and ground to proper shape forproducing best results.

The entire device is simple and inexpensive, may be easily andinexpensively manufactured and installed, and is in every way highlyefficient and desirable, and since probably the best results may beobtained from the details disclosed, such details may well be followed,but I wish it understood that I within the scope of the invention asclaimed,

15 zontal supporting bars having central open- I said tubes; of aplurality or standards ris from said headers at spaced points and havingaligned bearings, a horizontalshaft rotatably mounted in saidbea-ringsand hav ing a plurality of spaced sprocket wheels, chains trained oversaid sprocket wheels, vcrtuzal rods secured to and depending from thelower ends of said chains, said rods being slidably receiyed betweensaid headers, horiings through which the lower ends of said rods pass,nuts threaded on said lower ends or the rods for supporting said barsand permitting slight vertical adjustment there of, a plurality ofzig-Zag fluid spray pipes resting removably on said supporting bars andloosely received between said water tubes, means for supplying fluid tosaid spray pipes while permitting Vertical movement thereof, and meansfor driving the aforesaid shaft in either direction.

In testimony whereof Ihave hereunto set my hand.

JAMES ANDERSON.
